, tating a blank, parallelogrammic in outline,

and the means for advancing the blank to the'patch applying mechanismand Fig. 12

is a partial vertlcal section and front viewv on. This type ofimachinecombines the advantagesof simplicity, speed of operation and accuracy 1ncarrying out the steps neces sary to make a complete envelop. Blanks ofthe shape shown in Figs. 3, 5 and 11 may be cut by revoluble cutters inthe machine, (Figs. 3 and 11) from a roll of paperand then advanced tothe patch applylng means, or suitable blanks already cut maybe fed tosald patch applying means by any of the feedlng devices well known inthe art, and which devices are not shown in the drawlngs. f

The blank cut by the mechanism shown in Figs. 11 and 12 is of the formwell known in the art, being substantially parallelogrammic in outline,thereby economizing in paper. The feeding mechanism comprises feed rolls26 and 27 on shafts 42 and 43' 'i respectively, mounted in frames 1 and2, said feed rolls coacting to advance the web of i paper 63, which issupplied from a suitably supported roll of paper not shown. Revolublecylinder 28 on shaft 44 carries the four cutters 67, 68, 69 and 70 formaking the edge cuts in Web 63. Said cylinder 28alsov by suitablemechanism said chips being withdrawn by a suction pipe or other suitablemechanism not shown, or dropped into a receptacle provided therefor. Thecutting mechanism shown in Figs. 11 and 12 differs from that shown inFigs. 3 and 4 only as regards the shape of the blank shaping and blanksevering cutters and the-description given above will suflice for both.

Referring now particularly to Figs. 11 and 12, segmental cylindricalroll 32 0n shaft 51 coacts with roll 33 on shaft 52 .for advancing thecut blank. Short cylindrical segmental -blank advancing roll 34 on shaft53 is placed as close as is permissible to conical rolls 40 and 41 onshafts 55 and 56 reand 41 is preferably in the plane of advance of theblank, said plane being preferably horizontal, the axes of said rollstherefore converging so that shaft 55 carrying roll. 40 must beterminated at some point preceding the intersection of the axes of saidrolls, the shape of which is preferably that of frustra of cones. Stand62 placed in advance of theA intersection of the axes of said conicalrolls supports shafts 55 and 56 placed-diagonally of the machine andinclined downwardly and upwardly respectively. Supports 64 and 84 arealso provided near the extremities of shafts 55 and 56.

Short segmental blank forwarding roll 36 on shaft 58 coacts withrevoluble roll 37, both of said rolls being placed as close as ispermissible to conical rolls 40 and 41 without interfering therewith,said rolls 36 and 37 coacting to gri blank 65 when the conical rollsrelease t eir hold, to advance the blank without interfering with therotation of the blank. Segmental roll 38 co-acts with revoluble roll 39for advancing the blank to the patch applying means and is sovgeared andof such diameter as to increase the' speed of travel of the blank toallow time for the stopping of. said blank later for the furtheroperation thereon as hereinafter described. Said roll 38 acts in thesame manner and has the same function in Fig. 11 and in Fig. 3, and thedescription givenapplies to both gures.

The operating mechanism of the parallelogrammic blank cutting machine isas follows: pulley 3, obtaining power from a source not shown is mountedon shaft 42 as is gear 4, which drives gear 5 on shaft 46. Cuttercarrying cylinders 28 and 30, chip gripper roll 60 and se ental rolls 32and 34 together with the ro s coacting therewith, are driven by gear 5,through the train of gears, 6, '7, 8,19, 10, 11, 12, 13 and 14, t0-

i shaft 57 supported in frames 81- and 82, and

gear 15 on the same shaft through the train of gears 15, 155, 154, 152,151 and 310 acting together with' suitable gears not shown.

The conical rolls 40 and 41 are used 'to turn the blank 65 from theskewed in which it is cut from the web 63 1nto the proper position foreasy further operation thereon, such as patch applying, folding andgumming. In connection with the cutting mechanismdescrihed above, theatcli applyosition ing means shown in Figs. 1 an 2 or Figs.l 7 vand 8maybe used, as shown in Figs. 3

and 4.

Referring to Figs. 1 and 2, forwardin vrolls 135 and 136 take hold ofthe blan after it has been severed from the web and properly speeded up,or after it has. been fed to said forwarding rolls by a' suitablefeeding device not shown.

interfering with the patch applying operation. Gum is supplied togumming ledge 137 by 'gum roller 130 revolving in gum box 129.

is positioned directly under belts 94 to support the blank during theapplication of the patch. Oscillatory'alining stops 127 on Said rolls135 and 136 are mounted on shafts 209 and 210 Plate 95 is supported onrods 126 mounted in the side frames 8l and 82 andv shaft 223 are timedto engage the leading corners of the blank to stop andlproperly aline vsaid blank, after which oscillatory presser feet 87 mounted on shaft 205come down on and hold the blank stationary on the belts 94, until thepatch has been applied and the blank is ready to be advanced again. Thehopper 139, holding a pile of cut patches 131, and comprising plate 96having attached thereto rods 97 with toes 138 at the lower end of saidrods to support the pile of patches, is'supported by a bar 98 bent atright angles and having 'a dovetail shaped portion to fit a dovetailslot in frame 82, said ar 98 and the hopper 139 attached thereto beinggiven a reciprocating vertical motion l as hereinafter set forth. Selental roll 89 on shaft 218 coacting with rol .90 on shaft217,

is timed to grip the leading ilap of the blank.

when said blank is released bypresser feet `87. Roll 90 carries belts 94and with segment 89 advances the blank for further operation-thereon,such as the gumming of the `bottom seam. Strips of gum are preferablyplaced on the under side of the side flaps by gumming ledges 106 on roll91 mounted on shaft 220, said ledges 106 receiving the gum from gumroller 122 on shaft 222, said gum roller rotating in gum box 128. Dlsksas 93 on same roll 91 coacts with roll 92 on shaft 221 forl advancingthe blank continuously to suitable mechanism for completing the envelop,as for instance folding devices, shown conventionally in Flg. 1.

For the hopper 139 land the pile of cut 'patches 131 may be substitutedthe roll of paper 140 and suitable means for feeding 'and applying astrip of said roll. (Flgs.

and 8). Rolls 141 and 142 on shafts 143 and 144 respectively,intermittently feed the paper over guide 147 having an upwardly inclinedcutting edge 148 and supported to the side frames by rod 149, said paperpassing under blade 150, which is supported in a manner similar tohopper 139 by a bar similar to bar 98, as 298. Edge 148 and the edge ofblade 150 are positioned in the same vertical plane so that a downwardmovement of blade 150 shears ofl" a strip of paper and carries said cutstrip down to the blank, which is positioned with the gummed windowunder blade 150, whereby said strip is pasted over said window.

The actuating means for the blank advancing and patch applying mechanismis as follows: Segmental advancing roll and speeding up gear 154, whichis driven from another part of the machinel through gears 151, and 152(Fig. 3) and gear 155 (Fig.

10) in turn drives forwarding roll gear 109. Through the latter rotationis transmitted to the'gear 110 of the coacting roll on shaft 210.Gumming roll 85 is driven through gears 111, 113 and 112, while rolls89, 90 91 and 92 are driven by the train of gears 114, 115, 116, 117,118, 119, 120 and 121. The oscillatory motion of presser feet 87 isobtained through cam 103 on intermediate shaft 214, said cam rockingshaft 20'5 through l roller 104 and link 105. Stops 127 on hub 88 andoperating in slots 99 of plate 95 are given their oscillatory movementby cam 125 on shaft 218 through roller 124 and link 123 attached toshaft 223. The reciprocating motion of hopper 139 and of knife blade150,v

is obtained through rollers 101 and 132 at the end of bars 98 and 298respectively, said rollers being operated by cam 102 on shaft 215. Theintermittent motion of rollers 141 and 142 is given by ratchet wheel 145onv shaft 143 through pawl 146 operated by forked lever 157 having aroller 133 actuated by cam 156 on shaft 216.

It'is evident that the shape of .the blank suitable mechanism andspeeded uivby segment 38 is. passed on to the forwar ng rolls 135 and136 which advance said blank to gumming roll 85, where a strip of gum iseration of my improved machine applied around,- the window of the blank,

and the blank passed on tothe belts 94. Said `belts carry the blankforward to engagement withalining stops 127, which are timed tooscillate downwardly to en age the leading flap ofthe blank. The lts 94cause the blank to tend to move forward, the blank thereby adjustingitself until stops 127 engage the leading corners -of the blank, when'lthe blank can no4 longer slip and .is therefore properly alined. Theblank is held at rest on to the belts in its alined position by theoscillatory presser feet 87,- which come down on the blank and hold saidblank stationary justl as stops 1,27 movel away from the blank corners.Said blank is held stationary while hopper 139 or blade 150 come downover the gummed opening with the pile of patches 131 or the cut strip ofpaper respectively. In the case of the pile of patches 131, the lastpatch will adhere to `the gummed surface, -and on the upward movement ofthe hopper, will be drawn'out from toes 138 of rods 97 and separatedfrom the remainder of said pile. Presser. feet .87 are now raised,allowing the blank to be continuously forwarded by segmental roll 89, I

which is timed to grip the blank just as said presser feet let go. Saidblank may now be continuously advanced tothe bottom seam gummer 91 andto any vother mechanism for further operating thereon.
